Reaction Steps

A solution of cyclopentenone (1.23 g, 15 mmol), pentanal (1.94 g, 22.5 mmol), rac-1,1′-bi-2-naphthol (429 mg, 1.5 mmol) and tributyl phosphine (606 mg, 3 mmol) in dry THF (12 ml) was stirred at 20° C. under Argon for 3 hours. The solution was then passed through a short column of SiO2 (cyclohexane/Et2O 6:4) to obtain the pure title compound in 92% yield.
